前言 一次學習過程中簡單的記錄

這里就不多說了，下載安裝好Redis，最好是把Redis Desktop Manager一起安裝了，可視化看的舒服一點。

1.引入庫，配置yml

引入Redis依賴

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId></dependency>

這里就簡單配置做示例，小伙伴們根據自己的業務需求來配置哈~

server: port: 8081spring: redis: database: 3 jedis: pool:max-active: 8max-wait: -1 lettuce: pool:min-idle: 0 timeout: 5000

2.編寫RedisConfig

@Configurationpublic class RedisConfig extends CachingConfigurerSupport { @Bean @SuppressWarnings('all') public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();StringRedisSerializer keySerializer = new StringRedisSerializer();GenericFastJsonRedisSerializer valueSerializer = new GenericFastJsonRedisSerializer();redisTemplate.setConnectionFactory(redisConnectionFactory);// 序列化 key 和 valueredisTemplate.setKeySerializer(keySerializer);redisTemplate.setValueSerializer(valueSerializer);redisTemplate.setHashKeySerializer(keySerializer);redisTemplate.setHashValueSerializer(valueSerializer);return redisTemplate; }}

3.編寫RedisUtils

@Componentpublic class RedisClient { @Resource private RedisTemplate<String, Object> redisTemplate; /* * @ClassName RedisClient * @Desc TODO 設置緩存（沒有時間限制） * @Date 2021-07-24 16:11 * @Version 1.0 */ public void set(String key, Object value) {redisTemplate.opsForValue().set(key, value); } /* * @ClassName RedisClient * @Desc TODO 設置緩存（有時間限制，單位為 秒） * @Date 2021-07-24 16:11 * @Version 1.0 */ public void set(String key, Object value, long timeout) {redisTemplate.opsForValue().set(key, value, timeout, TimeUnit.SECONDS); } /* * @ClassName RedisClient * @Desc TODO 刪除緩存，并返回是否刪除成功 * @Date 2021-07-24 16:11 * @Version 1.0 */ public boolean delete(String key) {redisTemplate.delete(key);// 如果還存在這個 key 就證明刪除失敗if (redisTemplate.hasKey(key)) { return false; // 不存在就證明刪除成功} else { return true;} } /* * @ClassName RedisClient * @Desc TODO 取出緩存 * @Date 2021-07-24 16:12 * @Version 1.0 */ public Object get(String key) {if (redisTemplate.hasKey(key)) { return redisTemplate.opsForValue().get(key);} else { return null;} } /* * @ClassName RedisClient * @Desc TODO 獲取失效時間（-2：失效 / -1：沒有時間限制） * @Date 2021-07-24 16:15 * @Version 1.0 */ public long getExpire(String key) {// 判斷是否存在if (redisTemplate.hasKey(key)) { return redisTemplate.getExpire(key);} else { return Long.parseLong(-2 + '');} }

4.編寫Controller測試

@Controller@ResponseBodypublic class CaptchaController { @Resource private RedisClient redisClient; @GetMapping('/captcha') public void captcha(HttpServletRequest request, HttpServletResponse response) throws Exception {SpecCaptcha specCaptcha = new SpecCaptcha(130, 48, 4);specCaptcha.setFont(Captcha.FONT_1);String id = UUID.randomUUID().toString();response.setHeader('id', id);CaptchaUtil.out(specCaptcha, request, response);String verCode = specCaptcha.text().toLowerCase();redisClient.set(id, verCode);//可設置有效時間，單位為秒 } @PostMapping(value = '/check') public boolean check(@RequestBody String info) {JSONObject jsonObject = JSON.parseObject(info);String id = jsonObject.getString('id');String code = jsonObject.getString('code');String s = redisClient.get(id).toString();//idreturn code.equalsIgnoreCase(s); }}

訪問localhost:8081/captcha 別忘了啟動Redis

這里的id就是存進Redis的鍵

我們拿到Redis的鍵再去請求 localhost:8081/check 驗證我們的驗證碼是否是正確的
